HOPPER-CAR.

To all whom it may concern:

Be it known that I, WALTER P. MURPHY, a citizen of the United States, residing at New York in the county of New York and State of Blew York, have invented certain new and useful Improvements in-Hopper- Cars, of which the following is a specification.

My invention relates to hopper cars of metal construction. Cars of this type are constructed in various ways but with the general purpose of dividing the space within the car body into anumber of discharging chutes or hoppers having openings closed normally by hinged doors, throu h which openings the load is dumped. v T e fixed'portions'of the bottom of the car consist of inclined sheet metal st uctures, or

slope sheets, which are arranged so as to' direct the cargo to one or other of the discharge openings. Cars of this type are frequently loaded by means of clam shell buckets, or other loading or conveying devices,

which drop their charges often at a considerable distance above the car. As a result the bottom sections or slope sheets of the car'are soon worn, broken or otherwise injured and made unserviceable.

One of the principal objects of the present invention is to strengthen these portions of cars of this general type so as to thereby increase their durability under service conditions.

The invention consists of the new and improved constructions, arrangements and devices to be hereinafter described and claimed for carrying out the above stated objects and such other objects as willappear from the following description of certain preferred embodiments of the invention as shown in the drawings. For the purpose of illustrating the invention in a typical form my im provements have been shown in connection with a hopper car which in other respects is of familiar construction. It will be realized, however, that the invention is not to be limited to this particular species of car.

In the drawings, V

Fig. 3 is a similar view illustrating a modification.

Like characters of reference designatelike parts in the several figures of the drawings.

Referringlto the drawings- 10 deslgnates one of the side Walls of a car and 11 one of the end walls thereof. In the car of the general design illustrated, the space between the side and end walls is divided into four discharging hoppers or chutes each having a discharge opening. The drawings are fragmentary, showing one end ofgthe car only. Each discharge openmg is normally closed-by a door and these doors are operated in pairs, the doors at each end of the car being connected by a common cross beam. Longitudinal and transverse structures divide the bottom of the car into the four discharge hoppers mentioned. All of this is a matter of common construction. It will be sufficient to describe in detail a novel feature of the car, confining attention to one end of the car as shown in the drawings.

The end bottom section or panel 12 of the car slopes from the end wall 11 down to the discharge openings 13 and consists preferably of a fiat central strip M and two side plates or slope sheets 15, 15. This structure is riveted to the side and end walls in the usual way and is sustained by supporting devices which need not be described in detail. The longitudinal structure dividing this end of the car body into the two discharging hoppers mentioned consists of a sheetmetal member 16 pressed to approximately V-shape in cross section and trig angular side plates 17 which are riveted to the slope sheets 15. The outer walls of the discharge hoppers are composed of plates 18. The bottom part of the space within the car body is divided by a transverse structure consisting of two oppositely inclined panels 19, 19 which slope downwardly toward the discharge openings. Each of the panels 19 consists preferably of a middle sheet or plate 20 and side plates or slope sheets 21, 21. 1

It will be clear that the sloping sections 12, 19 will be subject to considerable wear and tear especially when the car is loaded will be particularly the case with the lengt and gradual inclination. Moreover, \these portions of the car, especially thefend bottom panel 12, have to carry the weight of 'the cargo in transit and are subject to wear when the cargo is discharged. To increase tudinally exten their strength and durabilitythese portions of the car structure are provided, in accordance with my invention, with rigidifying corrugations. For example, the slope sheets 15 may be provided, as shown in Figs. 1 and 2, with a lurality of parallel longiding. corrugations 22 which merge one into the other so as to give the sheets; a sinuous configuration in cross section, the corrugations terminating within the edges of the sheets" so that they act effectively as beams. In the figures mentioned the corrugations run longitudinally of the sheets, that is, in the direction'of the i movement of the load in discharging so that they do not interfere with, but rather from" facilitate, the dumping of material the car. If desired, the middle slope sheets 21, 21"may also be provided withlike'rigidi fying corrugations 23.

In Fig. 3 an arrangement is shown in which the slope sheets 15 15 are formed each with two sets of diagonally disposed corrugations 26 which extend from the lat eral edges of the sheet toward the center thereof and downwardly toward the discharge openings; the sheets being preferably formedalso each with a central longitudinal strengthening rib or corrugation 27. By

this arrangement the sheets are rigidified" both longitudinally thereof and also transversely, and the disposition of corrugations is such as to interfere very little, if any, with the movement of the load in disc; arging. The slope sheets 21', 21". at'the mi dle of the 'car may be provided with a similar arrangement of longitudinal corrugations 28 and diagonal corrugations 29. I

A corrugated sheet metal door 30 is provided for closing the discharge opening 13 which is hinged to the car body at 32, but as this structure is not claimed herein, being the subject matterof a copending applicatlon filed Feb. 9, 1921,.Serial No1'443,691, as 'a division hereof, detailed description 'of the same herein is unnecessary.
